<h1>Semantics</h1>
<div class="section" id="semantics-typedefs">
<span id="typedefs"></span><h2>Semantics: typedefs</h2>
<p>Notice how these two types differ:</p>
<ul>
<li><p class="first"><tt class="docutils literal">typedef T* value_type;</tt></p>
<blockquote>
<ul class="simple">
<li>notice this has pointer type</li>
</ul>
</blockquote>
</li>
<li><p class="first"><tt class="docutils literal">typedef T&amp; reference;</tt></p>
<blockquote>
<ul class="simple">
<li>notice this is not a pointer type</li>
</ul>
</blockquote>
</li>
</ul>
<p>This is done to be able to add pointers directly
to the container, but to hide the pointers externally.</p>
<!-- - ``typedef *implementation defined* object_type;``
- this is ``T`` for sequences and sets
- this is ``std::pair<const Key, void*>`` for maps -->
<p>Also notice that</p>
<ul class="simple">
<li><tt class="docutils literal">typedef ... iterator</tt></li>
</ul>
<p>allows one to iterate over <tt class="docutils literal">T&amp;</tt> objects, not <tt class="docutils literal">T*</tt>.
Note that:</p>
<pre class="literal-block">
iterator i = ...;
i.base();
</pre>
<p>returns an iterator that allows one to iterate over <tt class="docutils literal">void*</tt>
elements (<em>this is very rarely needed and you should not use the
functionality unless you know what you are doing</em>).</p>
<ul class="simple">
<li><tt class="docutils literal">typedef ... auto_type</tt></li>
</ul>
<p>This declaration hides a pointer pointer type. You can rely on the following
operations</p>
<pre class="literal-block">
T* operator-&gt;() const;
T&amp; operator*() const;
T* release();
~auto_type();
operator <em>implementation-defined bool</em>();
</pre>
<p>The destructor will delete the stored object <em>using the clone allocator of the container</em>
(this explains why we cannot use <tt class="docutils literal"><span class="pre">std::auto_ptr&lt;T&gt;</span></tt> nor <tt class="docutils literal"><span class="pre">std::unique_ptr&lt;T&gt;</span></tt>). It might help to
think it is just a <tt class="docutils literal"><span class="pre"><a class="reference external" href="compatible_smart_ptr.html"><em>compatible-smart-ptr</em></a>&lt;T&gt;</span></tt>. You can also return
the pointer from a function or assign it to another pointer via the <tt class="docutils literal">move()</tt>
function</p>
<pre class="literal-block">
auto_type ptr   = ...;
auto_type other = boost::ptr_container::move( ptr );
return boost::ptr_container::move( other );
